Comparisons

The terminology ‘potential difference’ is a very comprehensive term and discovered in so many energy disciplines like electrical and magnetic fields, however, Electromotive Force (EMF) is solely used in the electric circuits. Though, both terms are measured in unit Volts (V), there are significant differences between them. Electromotive force (EMF) …

A galvanic cell is the one in which an oxidation-reduction chemical reaction occurs spontaneously to generate electrical energy. Chemical energy is converted into electrical energy. An electrolytic cell is the one in which electrolysis process takes place, a chemical compound is disintegrated by passing electricity through it. The chemical reaction …

An Electric field takes place where a voltage exists. They are produced around appliances and cables since a voltage exists. If the voltage is higher, an electric field is stronger and its strength is measured in volts per meter (V/m). The field strength diminishes quickly as we move away from …

The primary difference between the analog and the digital filter is that a digital filter needs to sample the input signal (analog signal) and then convert it into binary numbers. These numbers are stacked (stored) as digital data in a system hard drive, treated, and manipulated digitally. On the other …

DC motor and DC generator are similar from the mechanical perspective, however from a technical stand point, both differ from each other significantly. The most significant difference between DC motor and DC generator lies in the conversion mechanism. DC motor converts electrical energy into mechanical energy whereas DC generator converts …

Current Transformer Current transformers (CT) are broadly employed in order to measure high magnitude currents. Such transformers basically step down (lower) the current which is to be measured, so that it can be measured with an average range ammeter. A CT generally possesses one or few primary turns. The primary …

Core type Transformer In core type transformers, winding is positioned on two limbs of the core and there is ONLY one flux path and windings are circumventing the core.     These transformers are quite favorite in High voltage practical applications like Distribution, Power, and Auto-Transformers. Shell Type Transformer In …

This article covers the key differences between Conductor, Semiconductor, and Insulator on the basis of Conductivity, Resistivity, Forbidden Gap, Conduction, Band Structure, Current Flow, Band Overlap, 0 Kelvin Behavior, and Examples.The following table covers the key Differences between Conductor Semiconductor and Insulator. Difference between Conductor Semiconductor and Insulator Difference between Conductors, …

A fuse and circuit breaker both of them protect an overloaded circuit by disrupting the current continuity. The way they disrupt the current flow is dissimilar. A fuse is a simple piece of metal that melts down when overheated because of excessive flow of current whereas a circuit breaker has …

Capacitor and inductor fall under the category of passive components which store and release the energy but do not consume it. Both of the components are extensively used in several applications related to AC systems, especially in signal filtering. The main difference between the capacitor and the inductor is that …

Brushless DC motors are the one which use an electronic commutation and are powered through a DC source using switching supply and an inverter, which basically generates an AC electrical signal for driving the motor in order to drive the motor. Performance is the main concern for such motors and …

Capacitor and battery both perform the same function of storing and releasing an energy, however, there are essential differences between both of them due to how they function differently. Capacitors store energy in the form of an electric field while batteries store energy in the form of chemical energy. The …

The AC drives operate with AC signal or voltage, for instance, 1-phase or 3-phase AC voltages whereas DC drives operate with DC signal or voltage, for instance, DC supplies, and Batteries. Generally, a DC drive changes an Alternating Current (AC) into Direct Current (DC) using a converter (Rectifier) to operate …

In two winding transformer, whole power is transferred from primary to secondary side by means of induction ONLY While, in the case of Auto transformer, part of the whole power is transferred by induction and rest of the power is transferred through conduction. In two-winding transformers, primary and secondary windings …

Analog signals and Digital signals are the two categories of signals. These signals are utilized in order to broadcast different types of information. Analog signals are the ones that observe analog methodology to broadcast information in such a fashion that they can be analyzed at any instant of time while Digital …
